NVIDIA RTX 5070 Ti vs AMD RX 7900 XTX for local LLMs
50 reports on the NVIDIA RTX 5070 Ti and 46 on the AMD RX 7900 XTX
Which is faster for local LLMs?
On Gemma 4 26B · 4B active at 4-bit, the NVIDIA RTX 5070 Ti has 137.7 generation tokens/s (one run); prompt processing 5951.0 tokens/s (one run); the AMD RX 7900 XTX has 142.8 generation tokens/s (one run); prompt processing 4331.2 tokens/s (one run). Those are community reports whose engines and settings differ, so the gap is a rough sign, not a controlled measure of the two cards. Memory bandwidth, which caps how fast a card can write, is 7% higher on the AMD RX 7900 XTX (896 GB/s on the NVIDIA RTX 5070 Ti, 960 on the AMD RX 7900 XTX).

Measured on both
Generation and prompt processing speeds from plain runs (one device, one request, no speculative decoding, the whole model in the device's memory) of the same model size at the same bit class. Each side shows the engines and reported context behind its median. Context can mean a configured window or prompt depth, so these are community comparisons with differing settings. How to read these

Estimated by the calculator
The quant the calculator recommends for each card and its estimated speed at a 32,768-token context with 32 GB of system RAM, from memory bandwidth and the model's shape. Where a model was also measured above, the measurement wins.
